Processing technology for sofa chair and device

Abstract

The invention discloses a processing technology for a sofa chair and a device. The processing technology comprises the following steps that various plate raw materials are subjected to cutting, planing, splicing and carving processes to obtain assembly accessories A; the assembly accessories A are assembled to obtain a sofa inner frame B; a plurality of serpentine springs are installed in the middle of a seat of the sofa inner frame B side by side, the serpentine springs are connected through connecting rods, and a sofa inner frame C is obtained; cloth strips are installed on the surfaces of the serpentine springs of the sofa inner frame C to obtain a sofa inner frame D; the inner side of an elastic sponge is coated with glue, and then the elastic sponge is adhered to the sofa inner frame D, and the sofa inner frame D wrapped by the elastic sponge is sewn through cloth, and a sofa chair E is obtained; and the sofa chair E is subjected to impact test, static pressure test, foot hanging test and drop test in sequence, and a finished product sofa chair is obtained after the test is passed. According to the processing technology for the sofa chair and the device, the service life of the sofa chair can be effectively prolonged; and the processing efficiency of the sofa chair is improved, and the labor intensity of workers is reduced.

Description

Technical field [0001] The present invention relates to a sofa chair, particularly a process and apparatus for a sofa chair. Background technique [0002] The sofa chair is a single sofa, generally divided into a leather sofa chair, fabric sofa chair and vine sofa chair, with fabric sofa chairs to integrate structural and detachable structures, one-piece structure refers to the sponge and The fabric is directly fixed to the sofa insert by paste, and the detachable structure is placed on the sofa rack after making a sponge and cloth into different shapes and functions, and the cushion can be placed as needed. And location adjustment. In order to improve the comfort of the sofa chair, the current sofa chair will also be set to the hollow structure at the sofa built-in chair, and set a snake spring spring in the hollow position, and support the external cushion using a serpentine spring. Make the user to feel flexible when riding. However, since the serpentine spring is fixed only a...

AI Technical Summary

Problems solved by technology

However, since the serpentine spring is only fixed at both ends during installation, it is prone to excessive bending or lateral deformation after long-term use, which affects the service life of the sofa chair

[0003] In addition, the current processing line for sofa chairs is relatively traditional, and many design defects of the original equipment have not been resolved, and its degree of automation and integration is relatively poor, which reduces the stability of sofa chairs in the process of processing, and Requires higher labor intensity of workers

For example, when cutting and engraving large-sized wooden boards, the existing board cutting machine cannot solve the natural bending of the board after being placed, so that the groove shape of the board after cutting will be twisted and deformed with the expansion of the board, and the depth will be different. question

Another example is that the existing jigsaw machine cannot solve the problem of heat preservation of the transmission equipment, and thus cannot improve the drying efficiency through a stable high-temperature environment during the drying process of the wood boards. It can only achieve the heating effect by direct blowing of hot air, so that the boards There are problems of low drying efficiency and poor drying uniformity during drying

On the other hand, since the existing processing equipment is single-function independent equipment, and there is no corresponding production line; the manufacturer needs to manually transport the blanks and semi-finished products during processing, which results in low transport efficiency and high work intensity. Big

However, the use of existing conveying equipment such as belt conveyors to replace manual conveying not only requires high equipment costs, but also requires a large floor space, and it is difficult to directly install it on the outside of existing equipment.

Therefore, the existing sofa chairs have the problem of short service life, and the existing processing devices for sofa chairs have the problems of low processing efficiency and high labor intensity of workers
